v0.6.0

Added

• LTE link monitor for nRF91

Fixed

• flushing of reconnect requests (there is no more unwanted reconnection when using credentials from
  Zephyr settings)
• documentation for settings in Github Actions HIL (Hardware In the Loop) tests

Breaking Changes

• calling golioth_rpc_register() no longer automatically observes. The RPC observation is now
  established only if the user calls golioth_rpc_observe(). Existing applications that use
  RPCs will need to call golioth_rpc_observe() in the on_connect callback. Additionally, it's
  recommended to move any calls to golioth_rpc_register() outside of the on_connect callback,
  to avoid registering the same RPC method multiple times. See the rpc sample for reference.
• calling golioth_settings_register_callback() no longer automatically observes. The settings
  observation is now established only if the user calls golioth_settings_observe().
  Existing applications that use settings will need to call golioth_settings_observe() in the
  on_connect callback. See the settings sample for reference.

Changed

• verified with Zephyr v3.3.0
• verified with NCS v2.3.0
• disabled sockets_offload_poll_wrapper by default (since there is proper fix in NCS 2.3.0)
• removed west projects filter in west-zephyr.yml to keep consistent behavior with west-ncs.yml
  (which is not filtered as well)
